Practice gradually becomes a systematic(?) you know just what you are doing. And you practice things. ???????????????? Then you do things, you work out things that are your weaknesses. And yoou pick up all the things about it, all the things that are going, and keep working on those. You pick them up, it may be individually in each scapes. Until you lick it,until you lick the problem. Many students are afraid of scales. Because number one they don't practice for it. And you know you are usually afraid of somthing you're not familiar with. You're weary; you stay away from it. In other words they are afraid of scales. ?, then scales being afraid of them. Many things are sorved during your practicing. It may take a long time, and it may be a very short time; and suddenly, things become clear. But duly(?) it must be old(?), during your work you'll find it. The matter you may have more time, you may hove less time,but you still have to do it. Then you're living for the immersions. But certain things are mechanical, but you have to do it systematically. You have to get your hands, your fingers and(or in?) shape. ?you know they just don't move, without two ? things. It has to be accordingly right? First , the fingers. Then your left hand with your right hand, that has to be syngcronised. If one is faster than the other...oh what a worse it is. One word is good. When I see "discipline", it said "the things you've got to and get along with, and so you do it". Discipline is important for your life anyway, for living. In fact I think discipline is important for enjoying life. You almost set to abuse yourself. Even you could get it, even you could get it, you shouldn't have abused it. In other words to say, if I have a little for tommorrow, I'll have a little bit for the next day. So that I enjoy each one fully. We have too much, too many comforts. Actually, thay're not contributed for dreaming ?????????
I don't think there is such a thing as tone-deaf(or tune-deaf). You haven't been exposed, and then take an effort to do it. In other words, the more you hear music, the more you will like it.
